    14

    Step-by-step explanation:

    Geometric mean = nth root (product of individual values of set of data)

    from the question, n=2,

    product of individual values of set of data = 2/5*490 = 196

    Therefore Sqrt (196) = 14

    NB: As n is 2, we use sqrt, if n is 3, we use cube root and so on
